Which academic paper does this implementation come from #2
Description
Hello,
I'm trying to study more about the origins of the nonuniform FFT.
It looks like the most recent research is from https://finufft.readthedocs.io/en/latest/refs.html, which derives from Greengard and Lee "Accelerating the Nonuniform Fast Fourier Transform", which in turn cites:
- A. Dutt and V. Rokhlin,Fast Fourier transforms for nonequispaced data, SIAM J. Sci.Comput., 14 (1993), pp. 1368–1393.
- and possibly: S. Bagchi and S. Mitra,The Nonuniform Discrete Fourier Transform and Its Applications in Signal Processing, Kluwer Academic, Boston, 1999.
Do you happen to know what the "canonical lineage" of the NUFFT is? Or, at least, the implementation in this codebase?
Thanks.
